Selective harvesting of two competing fish species in the presence of toxicity with time delay

作者：

Highlights：

• We study a delayed two species competitive fishery model.

• We consider a time delay in the harvesting term.

• We introduce the concept of selective harvesting in a two species competitive system.

• We study the effect of toxicity and time delay.

• Numerical examples support the model and analysis.
